`Be it known that I, CHARLES M.' Jaeeniis,

acitizen of the United States, and resident 1 such as will enable others skilledin the art to which it appert-ains to make and use `the saine.

vThe' Iinvention relates to elastic heels or treads essentially for boots, shoesmand the like, and has fr its object to provide'a tread of rubber or similar elastic material f provided 'with wear pieces embedded therein; the outer ends of 'which lie substantially in the plane ofthe tread surface, the' several Wear pieces being positivelyconnected in.

series by links or bars, which are Preferably formed integrallywith the wear pieces, so

that wlien'the'connected series of Wear pieces are embedded in the elastic body of lthe heel they will not only serve to increase the life and durability of. the heel, but will prevent the latter Wearing unevenly and becoming distorted orI deformed, and 'will moreover aiord efiicient means for attachment of the tread to the heel of theshoe. Furthermore, the positive connections between the several wear pieces will )revent any of the Wear pieces becoming loose andI dropping out, which isa serious objection in the old forms of wear pieces and reinforcing washers employedin elastic'heel treads.

the tread is a connected seriesof` ratenaai nee. -es, il f f Vwhich are centrally perforated a-ndadaptedV to receive the nails, screws, or similar fastenf ings g, by means of, which the tread is se-11 cured to the shoe heel. Between the tubular v members there is interposed a single connec tion, preferably in the form of relatively."`

light bars'e, the several members e'serving to l hold the several wear pieces together in f connected series, as more particularly illustrated in Fig. 3. necte'd with the wear pieces intermediate of the height of the latter, just above a circumferential 'shoulder Z1-with which each `Wear piece is provided, as shown in Fig. 3. i The wear pieces and their connecting bars may be made in continuous lengths by casting, molding, drop-forging, or the like, or-in the alternative, the wear pieces may be formed separately and the connecting members sub lsequently secured thereto.
